Fix PDF opened in GIMP by default

When Arch linux is used without a specific desktop environment like GNOME or
KDE, opening a file by xdg-open works incorrectly. Particularly, GIMP is
launched for PDF instead of a dedicated viewer. There are some details on the
Arch wiki page
xdg-utils. To fix the
issue, it’s necessary to install another application association handler.

Looking at the comparison table on the page Default
applications,
I decided to install
mimeo and
xdg-utils-mimeo.
Then to make sure Evince is launched to view a PDF file, did the following:

mimeo -d to list available desktop entries

mimeo --add application/pdf org.gnome.Evince.desktop to set the default
application
